United States Patent 3,341,962 BALL POINT PEN WITH PERMANENT DISPLAY ELEMENT Milton I. Siegel, New York, N.Y., assignor to Duro Pen C0., Kings County, N.Y., a corporation of New York Filed Oct. 4, 1965, Ser. No. 492,609 6 Claims. (Cl. 40-334) This invention relates to writing implements in general, and to a ball point pen in particular, which is equipped with facilities for visibly carrying a non-interchangeable message, such as an advertisement. The invention consists in the novel parts, construction arrangements, combinations and improvements herein shown and described.

It is an object of the present invention to provide a writing instrument, such as a ball point pen, wherein simple and efiicient means are arranged for holding and displaying indicia, such as a slogan, advertisement message, decorative design and the like.

A further object of this invention is to provide a writing instrument wherein displaying indicia are permanently incorporated.

Another object of this invention is to provide a writing instrument having incorporated therein displaying indicia which are protected against damage and which cannot be removed except by destroying the instrument.

Yet another object of the present invention is to provide a practical and useful article of manufacture which can easily and economically be mass-produced.

Various further and more specific purposes, features and advantages will clearly appear from the detailed description given below taken in connection with the accompanying drawings which form part of this specification and illustrate merely by way of example one embodiment of the device of the invention.

In the following description and in the claims, parts will be identified by specific names for convenience, but such names are intended to be as generic in their application to similar parts as the art will permit. Like reference characters denote like parts in the several figures of the drawing, in which:

FIG. 1 shows a longitudinal section of the ball point pen, partly broken away;

FIG. 2 shows the lower end of the ball point pen in a longitudinal section, in an enlarged scale, partly broken away;

FIG. 3 shows a longitudinal section of the lower end of the inner tubular member of the ball point pen, partly broken away;

FIG. 4 shows the view of the member shown in FIG. 3;

FIG. 5 shows a longitudinal section of the lower end of the outer tubular member of the ball point pen, partly broken away; and

FIG. 6 shows the view of the member shown in FIG. 5.

Referring now in more detail to the drawing illustrating a preferred embodiment by which the invention may be realized, there is in FIG. 1 a ball point pen generally indicated by the numeral 10, which comprises a cap 11 having a conventional mechanism therein for protracting and retracting a conventional cartridge 12 (mechanism not shown in the drawing). The lower end 11a of cap 11 is internally threaded so that the threaded upper end 13 of the opaque tubular inner body member 14 may be screwed into end 11a. Inner member 14 has a flange 15 which abuts against lower end 11a of cap 11. A washer 16 is provided between flange 15 and end 11a. The lower end 17 of inner member 14 has an internal shoulder 18 and the face of lower end 17 has a plurality of projections 19 (three are shown in FIG. 3).

A transparent tubular outer member 20 is fitted over lower face of the inner lower face of the outer inner member 14 in such manner that the inner diameter 21 of outer member 20 is slightly larger than the outer diameter 22 of inner member 14. The space between outer and inner member is fitted with a thin sheet 23 bearing whatever indicia are desired. The lower end 24 of outer member 20 has a flange 25 which has a number of cut-outs 26 corresponding to projections 19 of inner member 14. The length of thin sheet 23 is such that it fits precisely between flange 15 of member 14 and flange 25 of member 20 after the two tubular members are fitted together. Projections 19 engage cut-outs 26 so that after assembly members 14 and 25 cannot be rotated upon one another. A conventional conical hollow tip 27 having a cylindrical tubular neck 28 is inserted into a bore 29 of inner member 14. Tip 27 has a shoulder 27 at the point where neck 28 starts, so that shoulder 27 may be solidly abutted against flange 25 of member 20. Tubular neck 28 eventually is crimped over shoulder 18 at final assembly forming a small flange over said shoulder, so that the two tubular members 14 and 20 with sheet 23 between them form, together with tip 27, a complete unit which can only be separated by willful destruction. Tip 27 has a conventional orifice 32 for the writing end 30 of cartridge 12. Neck 28 of tip 27 has such an internal diameter that cartridge 12 is slidably guided therein. A conventional compression spring 31 on cartridge 12 is arranged to be seated against the crimped end of neck 28 on shoulder 18.

It is obvious that the assembly comprising inner member 14, outer member 25, indicia sheet 23 and tip 27 remain undisturbed when cap 11 is unscrewed from threaded end 13 in order to insert a refill ink cartridge. Furthermore, any relative movement between inner and outer tubular members 14 and 20, respectively, is prevented so that any or all fine details or printed matter on sheet 23 are infinitely protected against damage or deterioration. Ball point pen 10 also retains its original identity and cannot be reused by a third person because indicia sheet 23 has become an integral part of the pen after final assembly.

While the invention has been described and illustrated with respect to a certain preferred example which gives satisfactory results, it will be understood by those skilled in the art after understanding the principle of the invention that various other changes and modifications may be made without departing from the spirit and scope of the invention and it is intended therefore in the appended claims to cover all such changes and modifications.

I claim:

1. In a writing implement having a ball point cartridge, a compression spring on said cartridge, a hollow cap having a mechanism located therein for protracting and retracting said cartridge, said cap having a lower end; the combination of a first tubular member having an upper end adapted to be secured to said lower end of said cap, an outwardlydirected flange on said first member adjacent said upper end, a plurality of projections on the lower end of said first member, said first member having an internal shoulder adjacent its said lower end, a second tubular member enveloping said first member, said second member having an inwardly-directed flange at its lower end, said inwardly-directed flange having a plurality of cut-outs adapted to engage said projections, a conical, hollow tip having an outer shoulder, said outer shoulder abutting against said inwardly-directed flange, a cylindrical tubular neck protruding over said outer shoulder, said neck fitting into said lower end of said first member, and a flange on said neck, said flange overlying and being in secure engagement with said internal shoulder in saidfirst member, whereby said first member, said second member, and said tip are permanently retained in assembled condition.
